6.10 DNS Proxy/Relay
DNS proxy receives DNS queries and forwards DNS queries to the Internet. After the
CPE gets answers from the DNS server, it replies to the LAN clients. Configure DNS
proxy with the default setting, when the PC gets an IP via DHCP, the domain name,
Home, will be added to PC’s DNS Suffix Search List, and the PC can access route with
“Comtrend.Home”.
DNS Relay
When DNS Relay is enabled, the router will play a role as DNS server that send
request to ISP DNS server and cache the information for later access. When DNS
relay is disabled, the computer will pull information from ISP DNS server.
